I forget how many mills was shaved off with the head gasket and I know the heads were milled down. They have a tool to measure the all the cc's of the heads and pistons. I had a pic of them taking the measurements.
The pulley I'm running is 3.5"

When I added the meth injection and the 102mm TB on the old motor I picked up about 1.5LBS of boost just from those mods. The Whipple is set up for a TB up to 112mm. Everyone with a Whipple should run a 102mm.
